STAMP Raises €4M To Enhance Next-gen Tax Free Shopping For International Customers

In addition to private investment, the company has secured public grants from the Spanish Ministry of Industry and Tourism, the City of Valencia, the Community of Madrid, and the City of Madrid, reflecting alignment with public initiatives focused on digitalisation, tourism and the modernisation of commerce.

STAMP tackles inefficiencies in traditional VAT refund systems which rely on post-purchase reimbursements, intermediaries and complex procedures.

Its technology delivers tax benefits instantly at the point of sale, digitally integrating them into the payment experience while remaining fully compliant with European regulations.

STAMP’s model adapts to each country’s fiscal framework. In Italy, where regulations allow, purchases can be made VAT-exempt at checkout. In Spain, VAT is included on the invoice, but customers receive an instant discount equal to the VAT. STAMP validates transactions, ensures traceability and manages tax recovery including fraud scenarios allowing merchants to reimburse tax authorities without fiscal risk.

By reducing payment friction and simplifying access to Tax Free benefits STAMP enables merchants to turn Tax Free into a commercial advantage, boosting conversion rates, basket sizes and overall shopping experiences for international customers. Its integrated Tax Free and payments platform connects European retailers with global travellers and serves as a strategic partner for WeChat and Alipay.

“Tax Free, as applied until now, has operated more as an administrative procedure than as an automatic consumer right. When that friction is removed, customer behaviour changes, and merchants regain control over both the shopping experience and their margins,” said Abel Navajas, CEO of STAMP.

STAMP delivers, for the first time, a real Tax Free model that does not require regulatory change, provides maximum security and prevents fraud.

According to Navajas, the funding round strengthens STAMP’s ability to execute its roadmap and advance its mission of helping merchants in Southern Europe better serve international customers by streamlining payments and turning Tax Free into a tangible purchase incentive.

The funds will support expansion in Spain, Italy and Portugal and further product development, including advanced international payment solutions and a new AI-based offering.
